西北地区某列车整备库冬季供暖情况实测研究
Field measurement on winter heating performances of two railway depots in Northwest China
摘要
Abstract
The paper investigates the winter heating performance of two railway depots in the northwest China. The basic information of the heating system was first introduced. Then the indoor thermal environment, the operation of heating terminals and the cold air infiltration rates under different conditions were emphasized. The heating performances of the two workshops and the proportions of heating load were also compared. The results indicate that the operating performances are significantly different from the design conditions of the heating system. The hot air curtain is always open while the auxiliary heaters are usually shut. Consequently, indoor heat mainly comes from the radiator and heat leakage from uninsulated pipes. At the same time, the room temperature near the door is relatively low due to the cold air infiltration through the front door, which can be effectively improved by keeping the door closed. There are significant temperature gradients in the vertical direction for these workshops using radiators for heating.关键词
